Nuclear Criticality Safety Assessment of ORR, NBS, and HFBR Fuel Element Shipping Package

摘要

A fuel element shipping package employing a borated-phenolic foam as a thermal insulating material is designed to transport as many as seven fuel elements for use in the Oak Ridge Research Reactor, the Brookhaven Fast Beam Reactor, or the National Bureau of Standards Reactor. This report pre¬sents the criticality safety evaluation and demonstrates that the requirements for a Fissile Class I package are satisfied by the design.
